http://techbeasts.com/2013/12/18/how-to-unlock-bootloader-of-sony-xperia-devices-guide/
This guide is only for Sony Xperia Z1 C6903/2.
1. Do not try this on any other model, please check your device’s mode in Settings > About Device.
2. The CWM / TWRP recovery is only for Xperia Z1 C6903/C6902 running latest Android 4.3 Jelly Bean 14.2.A.0.290 firmware. Check your firmware version in Settings > About Device and make sure that it matches the one mentioned here.
3. You must have installed Android ADB & Fastboot drivers.
TO INSTALL ADB & Fastboot Drivers tool:
a. Download the Minimal ADB & Fastboot Drivers tool: Link 1 | Link 2
b. Run the minimaltool.exe file that you downloaded and install the tool.
c. You can run the tool now by either through the Start menu, through the icon that you created on the desktop or by opening Program files > Minimal ADB & Fastboot > Right click on an empty area while keeping the shift key pressed and click on “Open Command Window Here”. ( NOTE: just double clicking on the desktop icon opens the command prompt window)
d. Use the Command prompt to do whatever you want now!
e. To install any .img file, you will have to place that file in the Minimal Tool folder that is located under Program files. (in win8.1 its : C:\Program Files (x86)\Minimal ADB and Fastboot)
f. To access the Fastboot mode, you’ll have to first bring the Fastboot mode on your device and then connect it. E.g on HTC devices you can highlight Fastboot mode by accessing it through HBoot and then connect it, while on Sony you can turn off the device and then while keeping the back or volume up key pressed plug in the USB cable.
That’s All! You’ve successfully installed Android ADB & Fastboot drivers. I hope that it didn’t take more than 2 minutes for you.
4. Your device must have an unlocked bootloader. This is the slightly troublesome part but its straight forward.
How to Unlock Bootloader
Install Android ADB & Fastboot Drivers using the quick setup with Minimal tool. Find the guide here.
Now first of all you need to check if your device’s bootloader unlocking is allowed or not, to do so open the dailer on your device.
Type *#*#7378423#*#*.
As soon as you enter the above code, a menu will open up.
Tap Service info > Configuration > Bootloader Unlock. If it says Yes, that means bootloader unlocking is allowed, else you can also find out if the Bootloader is already unlocked.
Now in the dialer type “*#06#”, you should get the IMEI number of your phone. Note it down somewhere
After verifying the bootloader unlock permission, turn off your device completely.
Now open the Minimal ADB and Fastboot command prompt, that you created using the guide above.
Press the back key or Volume Up key on your Xperia Device and connect it to your PC while keeping the key pressed. The back key works for older Xperia devices, while for newer devices Volume Up key will work.
In case you are trying to unlock the bootloader of your Sony Xperia Z1, please make sure that it’s running on latest Android 4.3 Jelly Bean firmware. If you tried to unlock bootloader on Android 4.2.2 firmware, it will cause the camera crash on your device.
In the command prompt type: fastboot.exe -i 0x0fce getvar version and press enter, you should get a response now e.g (0.3). This step is to verify that your device is properly connected or not.
Now open this Pageand accept the legal terms and conditions by Sony to unlock the bootloader.
After accepting the legal terms and conditions, enter your name, your phone’s IMEI number (Remove the last digit of IMEI number) and your email and click Submit button
You should receive an email by Sony immediately, the email has the Key to unlock your phone’s bootloader.
Now again in the command prompt type this com: fastboot.exe -i 0x0fce oem unlock 0xKEY. Repalce KEY with the code that you got in the email by Sony and hit Enter.
As soon as you hit Enter, the bootloader will be unlocked and show you logs in the command prompt.
5 . Please make sure that your phone’s battery is charged at least over 60%. This is highly recommended in order to prevent any power issues during the recovery flashing process.
6. Please make sure that you backup all of your important media content, contacts, call logs and important text messages. This is highly recommended so that in case something goes wrong, you can still restore your data.
7. Use only OEM data cable to establish connection between your PC and Phone.
8. Now that the basics are done.... this is how to root
How to Install TWRP / CWM Recovery on Xperia Z1 C6903 and C6902:
Download your desired recovery.img file:
i recommend philz advance cwm , its easier and you arent required to download supersu
Philz Advance CWM Recovery for Xperia Z1 C6903/2
CWM Recovery for Xperia Z1 C6903/2
TWRP Recovery for Xperia Z1 C6903/2
Place the downloaded Recovery.img file in the Minimal ADB & Fastboot folder that you created using our ADB & Fastboot Quick Setup Guide.
If you are using Android ADB & Fastboot full package, you can place the downloaded Recovery.img file in the Fastboot folder or in the Platform-tools folder.
Open the folder where you placed the Recovery.img file. E.g Minimal ADB & Fastboot or Fastboot or Platform Tools. (in win8.1 its : C:\Program Files (x86)\Minimal ADB and Fastboot)
Press and hold the shift key and right click on an empty area within the folder, and click on “Open Command Window Here”.
Turn off your Xperia Z1 completely.
Now press the Volume Up Key and while keeping it pressed plug in the USB cable.
You should see a blue light in the notification light of your phone, that means your device is now connected in Fastboot mode.
Now type the following command: Fastboot Flash boot Recoveryname.img
You may rename the recovery.img file for your ease of access and replace it with Recoveryname in the command to flash it.
Hit Enter and it will quickly flash CWM / TWRP recovery in your Xperia Z1.
How to Root Sony Xperia Z1 C6903 and C6902:
WITH PhilZ Advance CWM without installing SuperSu:
Boot into recovery (when the sony logo appears on boot press volume up volume down until the recovery loads)
Select Reboot System Now
Select Root device
Your phone will restart
Congrats! You’re rooted now.
WITH SuperSu:
Download the latest SuperSu.zip file.
Place the downloaded SuperSu.zip file on your phone’s sd card.
Boot into CWM / TWRP recovery on your phone.
Select Install Zip / Install > Choose Zip from SD / Ext Sd card > SuperSu.zip
Select Yes and let it flash SuperSu.
As soon as flashing is done, reboot your device.
Find SuperSu in App drawer.
Congrats! You’re rooted now.

You could root Z1 by flashing 14.1.G.1.534 and root with rootkitXperia, but it was too late

I seems that the right command is "fastboot flash recovery twrp.img"
Unless you wanna install the recovery onto the kernel partition.

@OP: The correct command to flash the recovery is
fastboot flash recovery twrp.img
Please correct it in your post.

it does't work

Because the instruction in first post is incorrect, after you flashed recovery you also need to use this command: "fastboot boot recovery_image_name.img"
This is needed only to boot into TWRP for first time, if you intend on flashing custom ROM's then Format DATA,reboot to recovery again and you can use it normal.

Downgrade Orea beta to Nougat

Orea beta is great but battery drain so much.
for 30 min of screen use it used 11%, is it normal ?
and I am looking to go back to Nougat, could any one please tell me how can I go back.
Thank you.

are this instructions for downgrading ?
Set up your computer for flashing
Download the fastboot tool from the Android SDK Platform-Tools package
Add it to your path so the flash scripts can find it
Connect your Essential phone to your computer with a USB cable
Enable unlocking
Before you can flash a new image, ensure Developer options are enabled and OEM unlocking is turned on. To do this:
Tap Settings, then tap System > About phone
Scroll to the bottom of the page, then tap Build number multiple times until you see the pop-up message “You are now a developer” (It usually takes seven taps)
Go back one screen to System, then tap Developer options
Find the option: OEM Unlocking and turn it on
Fastboot mode
Put your Essential Phone into fastboot mode by doing either of the following:
Use the ADB tool packaged above to run the command: adb reboot bootloader
Reboot your phone while holding the Volume-down button
Unlock your bootloader
NOTE: Installing the factory image will erase all information from your device. So remember to backup your phone before continuing.
Run the command: fastboot flashing unlock
Press the Volume-down button to navigate to the YES option, then press the Power button to confirm
Flash your factory image
Download the factory image to your computer
Unzip the downloaded file
Go to where you unzipped the images
For Linux / Mac OS X - Run the command: flashall.sh
For Windows - Run the command: flashall.bat
https://forum.xda-developers.com/essential-phone/help

Yup those are them, I just did it yesterday.
Just an FYI, I found that putting Oreo on the phone resulted in ADB not working 100% anymore, such as attempting to reboot into recovery/etc. It would just reboot back into the O.S..
Here is what I did.
- download the current release you want to flash. (e.g. NMJ32F), then unzip it into a new folder.
- on your phone, verify that USB debugging and OEM unlocking are turned on in the developers menu.
- reboot your phone into the fastboot mode (power and volume down buttons)
- from your adb command line: type: fastboot flashing unlock
- This will make your phone show a new screen asking if you want to unlock the bootloader. Use the volume down to select YES, and hit the power button. It will now reboot and erase the phone. It will eventually end up booting up too request you setup the phone. (that is what it did for me.)
- reboot the phone back into the fastboot mode (power and volume down buttons)
- you should now see the bootloader listed as unlocked (vs locked)
- from your adb command line: type: fastboot devices (which should show your phones serial number and fastboot next too it.
- on your computer, using the command line, go to the unzipped folder of the NMJ32F build you downloaded
- in the folder there is a batch file you will run called flashall.bat. run it
- your phone will start flashing the NMJ32F build
- when it completes it will reboot a couple of times, erase the phone, and end up at the "lets get started" screen.
- reboot the phone back to the fastboot mode
- from your adb command line: type: fastboot flashing lock
- select the option to lock your bootloader. The phone will reboot/erase I believe, and then end up back to the "lets get started" screen.
- after you setup your phone, you can go back into the developers menu to turn off the oem unlocking
The above steps pretty much follow essentials instructions. (the essential instructions don't give some specifics.)
You are all done. (I recommend you review my instructions and the essential instructions carefully, don't copy paste commands as I may have spelled something wrong, etc.. Just wanted to give you a flow of the process.)

I cannot get past the flashall.sh command, says permission denied everytime. I am able to execute every command to that point with out any issues. I have downloaded the latest android platform tools, and my mac is on the latest version of macOS . I have also tried to flash every single image that is available on the essential dev webpage. Any ideas would be awesome, is in possible to side load using the adb commands from the recovery menu and avoid the fastboot mode all together.

The issue has something to do with Mac and the platform tools. I was able to downgrade with no problem using a friend's Windows PC.

Sorry for the silly question, but what does this statements means?
"Add it to your path so the flash scripts can find it"
Is there any better instructions for first time user which dont include instructions like above? Thanks.

Nothing confusing about that statement for Windows, MacOS or Linux.
A command path needs to exist so that when you type the command it can be found.

Back to Stock all in one - enable dm-verity, lock bootloader, flash latest OOS

I wanted to create a guide which is as simple as rooting a OnePlus 3T. I don’t know if it will work with the OnePlus 3. I’m not responsible for anything. You’re doing it on your own risk, so only do it if you know what you will do, now! It may brick your device.
This is the way it worked for me. I do not guarantee it will work for you!
READ THE WHOLE INSTRUCTIONS FIRST BEFORE YOU DO ANYTHING​
What we do:
- Flash TWRP
- Flash an old version of OOS
- Enable dm verity
- Relock the bootloader
- Flash the latest stock rom
What you need:
- Computer (Windows 7 or 10)
- USB Cable
- about 1 hour of your lifetime
YOU WILL LOOSE ALL YOUR DATA - ALSO THE INTERNAL STORAGE WILL BE DELETED (pics, music and all the stuff stored there)​
Download to your computer:
Latest TWRP for OnePlus 3T
https://forum.xda-developers.com/on.../recovery-official-twrp-oneplus-3-3t-t3543391
and
latest OOS from OnePlus for your 3T
http://downloads.oneplus.net/
THE USB DRIVERS MUST BE INSTALLED ON YOUR COMPUTER​
Download to the phone:
4.0.2 OOS Stock rom (post #2)
https://forum.xda-developers.com/oneplus-3t/development/recovery-twrp-oneplus-3t-t3507308
Flash TWRP:
1. Start your phone in fastboot mode (don’t connect to your PC yet!)
2. Open CMD as Admin (Windows start-menu - type “cmd”, right-click, run as administrator)
3. connect your phone
4. rename the file to “recovery” (don’t type “recovery.img” manually, only “recovery”)
5. type command “fastboot devices” -> device will be listed
6. command “fastboot flash recovery C:\Users\...\recovery.img” (the path where it’s stored)
7. done -> boot to recovery
8. disconnect your phone - leave CMD open
Flash OOS 4.0.2
1. Go into TWRP
2. wipe “System, Data, Cache, Dalvik”
3. Install OOS 4.0.2
4. reboot into fastboot
Enable dm-verity:
1. connect your 3T when it’s back in fastboot
2. type in CMD “enable dm-verity”
3. done - keep CMD open and the phone connected
Relock the bootloader:
1. type in CMD “fastboot OEM lock”
2. Warning message on your phone will pop up -> choose “yes” on your phone by using the volume buttons to lock the bootloader (keep CMD open)
Update to the newest OOS via “sideload”:
1. VOL down to boot into recovery
2. choose “Install from ADB”
3. “Upgrade Android from USB?” -> “Ok”
4. rename the OOS zip file to "update"
5. type in CMD “adb sideload C:\Users\...update.zip”
6. done
7. reboot the device - it will take about 10 minutes, DO NOT INTERRUPT THE PROCESS
Finish
Take your time! Don't do it if you're in a rush.
Please give me feedback if it worked for you or if I have to change something.

enable dm-verity doesnt work
"enable is not recognised..."

Did you check if the device is listed in fastboot?
You can also try the command "disable" and then "enable"
Sometimes you may need to do it first, even if it's disabled

Thanks for your threat. I tried this but had to do a couple things differently.
I think enabling/disabling dm-verity works only with old firmware.
What I used:
* 4.0.2 firmware from this threat https://forum.xda-developers.com/oneplus-3t/how-to/firmware-modem-collection-flashable-zips-t3565535
* latest oneplus recovery and rom https://downloads.oneplus.com/
* the recovery can be downloaded from a link on the bottom of the rom download site.
I started with twrp and a custom rom.
You need usb debuging enabled and adb and fastboot installed
What I did:
* I did a Nandroid backup, and copied the sdcards content to my computer, because the following completely wiped my phone
"adb pull /sdcard /path/to/my/drive/"
* flash 4.0.2 firmware, with trp
enter adb sideload mode in twrp and
"adb sideload firmware.zip"
* fastboot flash oneplus recovery
"fastboot flash recovery recovery.img"
* using onplus recovery and sideloading installed latest oneplus rom
enter adb sideload and
"adb sideload oneplusrom.zip"
* did a factory reset in oneplus recovery and cheked if my phone would boot
* entered fastboot mode
"fastboot oem disable_dm_verity", then "fastboot oem enable_dm_verity"
"fastboot oem lock"
after that my phone got wiped again, and the next boot took a long time
Then the phone was completely stock

Wanted to post to say thanks to roor7 and WhataHulk - had a rooted 3T I wanted to sell following an upgrade (best price requires the phone to have no sign of root!), and this was the only method that worked for me to enable dm-verity.
As a quick note, I followed roor7's guide, but got the same error message as chowchillacharlie. After sme playing about I found the simplest soultion was using the CMD line provided towards the end of WhataHulk's guide, i.e. - "fastboot oem disable_dm_verity", then "fastboot oem enable_dm_verity". For me, roor7's guide swapping the type "enable dm-verity" in CMD with "fastboot oem enable_dm_verity" worked a treat.
Sorry if that is all incredibly obvious to most people!
Thanks again gents.

sorry for taking so long in getting bk to u i decided to get rid of this device and got a pixel 3 xl thanks.

stupid Nokia, why bother rooting this with a pay service!
and a bunch of instruction, waste of time!
I own a xiaomi 9 se for unlocking BL just take a week, oneplus 6 just need a second!

I'm not saying anything about techmesto, but I do not know them. Man, do you know the damage someone can do with an IMEI and S/N? Damn Nokia.

Thanks for the super indepth guide! I've been waiting for years now for HMD to release the bootloader unlock tool for the OG phones, but that's clearly never gonna happen. Techmesto charges 8 dollars for the key and the downgrade + unlock, but 5 dollars for just the key. So I think I'll follow your guide to downgrade and then purchase the key from them afterwards.
